The Piston Ring Set 4.030 Classic Gold 1.5 1.5 3.0mm is an essential internal engine component designed for high-performance and classic engine rebuilds. Whether you're restoring a vintage small-block or upgrading a modified engine, this ring set delivers the precision gas sealing and blow-by control that separates a tight, efficient powerplant from a sloppy, inefficient one.
Built to Classic Gold specifications, these rings are engineered for engines running in the 4.030-inch bore range, making them ideal for mechanics and enthusiasts tackling serious engine work. This three-piece ring set features compression ring thicknesses of 1.5mm and 1.5mm, paired with a 3.0mm oil control ring, a proven configuration that balances ring durability with minimal friction and consistent oil film maintenance.
The Classic Gold material treatment provides superior scuff resistance and improved conformability to cylinder walls, reducing break-in time and extending ring life under demanding conditions. This piston ring set is best suited for experienced engine builders and mechanics performing complete engine overhauls, short-block assemblies, or restoration projects on classic and performance applications.
